Display device

Abstract

The present invention relates to a display device which directly executes searching related to text displayed on a screen, the display device comprising: a display unit for displaying content; a user input interface unit for receiving a control signal of a pointer being displayed on the content; and a control unit for, when a search command is received, controlling the display unit to display a search result of the text displayed on an area where the pointer is located.

What is claimed is: 
     
       1. A display device for performing a search, the display device comprising:
 a display configured to display content; 
 a user input interface configured to receive a control signal of a pointer displayed on the content; and 
 a controller configured to: 
 determine a search target based on a text displayed in an area in which the pointer is positioned, 
 control the display to display at least one search area icon for receiving selection for a search range after determining the search target, 
 control the display to display a search result of the search target within the search range corresponding to the selected search area icon, and 
 determine a text which has a hyperlink in the area in which the pointer is positioned as the search target. 
 
     
     
       2. The display device of  claim 1 , wherein the controller is configured to:
 extract the text from the area in which the pointer is positioned; and 
 determine the extracted text as the search target. 
 
     
     
       3. The display device of  claim 1 , wherein the controller is configured to, when the content is a web-browser:
 determine the text, which is in the area in which the pointer is positioned, as a search target, when the text has a hyperlink; and 
 control the display to display a search impossibility message, when the text, which is in the area in which the pointer is positioned, has no hyperlink. 
 
     
     
       4. The display device of  claim 1 , wherein the controller is configured to:
 determine whether the text is the search target, based on a position of the text on the content. 
 
     
     
       5. The display device of  claim 4 , wherein the controller is configured to:
 determine, as the search target, a text extracted from a title area of a banner, when the pointer positioned in the title area of the banner, when the content is the banner. 
 
     
     
       6. The display device of  claim 1 , wherein the controller is configured to:
 determine whether the text in the area in which the pointer is positioned is the search target based on a size of the text. 
 
     
     
       7. The display device of  claim 1 , wherein the controller is configured to, when the content is a mirroring image:
 receive, from an external terminal, a text in an area in which the pointer is positioned in the mirroring image; and 
 determine the text received from the external terminal as the search target. 
 
     
     
       8. The display device of  claim 1 , wherein the controller is configured to, when the area, in which the pointer is positioned, is an image:
 extract a text related to the image; and 
 determine the extracted text as the search target. 
 
     
     
       9. The display device of  claim 1 , wherein the controller is configured to, when a fixed text and a variable text is included the area in which the pointer is positioned:
 determine the fixed text as the search target. 
 
     
     
       10. The display device of  claim 1 , wherein the controller is configured to:
 recognize a command for selecting one area within a predetermined time, which is on the content, through the pointer, as a command for selecting the text displayed in the area in which the pointer is positioned; and 
 recognize the command for selecting the one area after a predetermined time, which is on the content, through the pointer, as a search command for searching for the text displayed in the area in which the pointer is positioned. 
 
     
     
       11. The display device of  claim 1 , further comprising:
 a voice acquisition module to acquire a search command, 
 wherein the controller is configured to: 
 acquire, as the search target, the text in the area in which the pointer is positioned, when receiving the search command through the voice acquisition module.
